Starlight generator

When Volvo diesel generator or transformer has overexcitation fault, it does not always cause obvious damage to the equipment, which is easy to be neglected. However, repeated over excitation will cause insulation aging and reduce the service life of the equipment due to overheating. The control of generator stator voltage is realized by adjusting the magnitude of rotor excitation current. The excitation corresponding to the amount of electricity generated is normal excitation. When the stator operating voltage is higher than the rated voltage, it is called overexcitation. Conversely, the stator operating voltage below the rated voltage is called underexcitation. In practice, there is a definite positive and negative value above or below the rated voltage. Different generators have different   excitation control system   and different excitation values. Generators and transformers are composed of iron core windings. If the applied voltage of windings is U, the ...

Preparation before starting diesel generator set ①   Complete inspection a. The switch of the control panel should be turned off before inspection, and be careful not to short-circuit the battery output electrode. b. Re-clean and inspect the machine room to ensure that there are no flammable and explosive materials around the unit, ensuring smooth and unobstructed air in and out of the machine room. c. Thoroughly inspect and ensure that the electrical and control parts are connected correctly, in good contact, reliable, and without aging. d. Check the reliability of the fastener and throttle adjustment system, confirm that the operating mechanisms are flexible, lightweight, and reliable, and check the pre-tightening of the water pump belt, charger belt and fan belt. e. Clean the surface of the   generating set , especially the rotating part of the unit to ensure that there are no foreign objects, check to ensure that there is no coolant, fuel, oil leakage. ...
